4 FAQs about What does BC mean for photovoltaic panels

What is a BC solar panel?

BC stands for “Back Contact.” These solar cells are different from regular ones. In normal solar panels, you can see thin metal lines on the front that collect electricity. But these lines block some sunlight. BC panels move all these lines to the back of the panel.

What is a BC solar cell?

This means the front of the cell, which faces the sun, has no metal lines (called gridlines) obstructing it. The concept of BC solar cells was first introduced in 1975 and has evolved over the years to become one of the most efficient solar technologies available today. How Does a BC Solar Cell Work?

Can BC solar cells be used with other solar technologies?

Versatile Use: BC solar cells can be combined with other solar technologies like PERC, TOPCon, and HJT to create even more efficient hybrid cells. For example, combining BC technology with HJT cells forms an HBC cell, which boasts very high efficiency rates.

Why are BC solar panels better than regular solar panels?

Without metal lines on the front, more sunlight hits the solar cells. This makes BC panels about 0.6-0.7% more efficient than regular ones. BC panels could someday reach 29.1% efficiency, which is really high for silicon solar panels. 2. They Look Better BC panels have a clean, all-black look with no visible lines.

What is a back contact solar cell?

Back contact (BC) solar cell, is a type of Si solar cell technology, where all the electrical contacts are located at the rear side (back side) of the device. In contrast, other Si solar cell
